With the recent change to ensure that submission side errors that
happen on behalf of an sqe are returned in the form of a cqe rather
than -1/errno from the system call, make sure that the man page
reflects that.

This cache hint has been removed from the io_uring series, as there's
some hesitation to leak this information to userspace. Remove it from
the header file and the man page. We can always re-introduce it later,
if we get some variant of this included.

min_complete means slightly different things depending on how the ring
was setup.

With a recent change to the kernel side, we now fully guarantee that
once io_uring_enter(2) returns that X entries have been submitted, it's
completely safe to reuse tohse entries. This used to not always be the
case, if an SQE had to be punted to async context for submission.
This makes for a more reliable and nicer interface.

The man page suggests that IOSQE_FIXED_FILE must be specified for all
sqes when the io_uring instance has files registered. This is not
the case, so clear that up.
Also fix a typo (few->new) while we're in there.
